UNITED STATES PATENT FFICE.

WILLIAM GOODWIN, OF SOUTH HAYLING, ENGLAND.

TAP.

To all whom it may concern:

Be it known that I, IVILLIAM GoonwIN, a subject of the King of Great Britain, residing at Park Road, South Hayling, Hayling Island, in the county of Hants, England, engineer, have invented certain new and useful Improvements Relating to Taps, of which the following is a specification.

This invention has reference to taps particularly applicable for use with drums, tanks and similar receptacles adapted to contain oil or other liquid, the chief object being to enable such taps to be readily and efficiently secured or fixed in any desired position for the purpose of drawing off the contents of the receptacle as required.

According to this invention the tap is attached or secured to the wall of the receptacle by the intervention of a connecting piece comprising an outer member and an inner member, the latter of which is provided with a number of fingers arranged and constructed in such a manner that when the tap spigot is screwed or otherwise attached to the inner member, the fingers will be forced outwardly and securely hold the tap upon the wall of the receptacle, the said. connecting piece by being drawn against the outer face of the receptacle affording a firm and tight joint.

In order that the said invention may be clearly understood and readily carried into effect, I will proceed to describe the same with reference to the accompanying drawings, in which,

F igure 1 a longitudinal section, and, Fig. 2 an end view of the connecting piece above referred to. Fig. 3 is a longitudinal section of the tap and connecting piece fitted together. Fig. 4 is a sectional plan of a plate hereinafter referred to carrying cutters for cutting the hole in the receptacle.

The connecting piece comprises an outer member C surrounding a hollow cylindrical inner chamber C screw-threaded internally for a portion of its length and having pivoted thereto a number of gripping members or fingers c. The member C is prevented from independent rotation by any suitable means, as for example, by a longitudinal projection 0 thereon working in a corresponding groove 0 in the outer member C. It is, however, capable of a certain amount of axial or longitudinal motion within themember C. the recessed chamber G enabling the pivoted ends 0 of the gripping members Specification of Letters Patent.

or fingers c to participate in such motion. The said gripping members or fingers 0 in the forward position of the member G ex tend beyond the outer member' C, and are provided at their free extremities with outwardly extending projections or teeth To fix the tap to the wall of the receptacle, the gripping members or fingers 0 are moved about their pivoted ends 0 so that the free extremities converge as shown in Figs. 1 and 2, in which position the projections or teeth 0 are capable of passing through the hole in the wall of the receptacle. Upon inserting the spigot A of the tap into the rear end of the member C the gripping members or fingers c are caused to spread and overlap the surface surrounding the hole in the receptacle. As the threaded portion A of the spigot A is screwed into the threaded portion of the member C the latter is drawn back, and the projections or teeth 0*, gripping the inner surface of the receptacle, force the outer surface thereof into close contact with the washer A. To afi ord additional security against the possibility of leakage, the projections or teeth 0 are slightly beveled on their hearing surfaces, as at 0*, so that during the tightening operation, the periphery of the hole or aperture in the wall of the receptacle is forced back and compelled to bite into the washer A*.

In some instances it may be desirable to remove the handle 13 of the tap, this being effected by any well known method; for example, by making a square end on the plug 1) and forming the handle B with a socket adapted to be applied thereto.

The lower end of the plug?) may be formed with a tapered screw a to which a disk or plate A, provided with blades or cutters a may be attached. The plate A has thumb pieces or projections a to facilitate its attachment to or removal from the screw and the blades or cutters may be integral 'with said disk or plate A as shown in Fig. 3,

or detachably secured thereto in recesses a by means of nuts a, as shown in Fig. 4. This arrangement forms a convenient means for cutting a hole of the required size in the receptacle and being mounted upon the tap is always at hand ready for use. To cut a hole, the point of the tapered screw a is first applied to the wall of the receptacle and the tap handle B turned; as the screw a pierces the said wall, the blades or cutters A are brought into contact there with, and during the advance of lZlIQSCIQ N a hole is cut of the required size.

What I claim and desire to secure by Letters Patent of the United States is 1. A connecting piece for a tap compris ing an outer member and a co-axial inner member forming no part of the tap but having a sliding movement relatively to each other, a series of gripping members pivoted each at one end in the wall of the said inner member so as to form part of said wall when spread to their gripping position, outwardly projecting teeth on the free ends of .said gripping members where they extend beyond the wall of said inner member, and means for spreading said 'rippin g members;

2. A connecting piece for a tap comprising an outer member and a co-aXial inner member forming no part of the tap but having a sliding movement relatively to each other, a series of grinning members pivoted each at one end in the wall of the said inner member so as to form part of said wall when spread to their gripping position, outwardly projecting teeth on the free ends of said gripping members where they extend beyond the wall of said inner member, and means for engaging said inner member with the snigot of the tap so that the spigot spreads the gripping members.

r 3. ii connecting piece for a tap comprising an outer member and a co-axial inner member forming no part of the tap but having a sliding movement relatively to each other, a series of gripping members pivoted each at one end in the wall of the said inner member so as to form part of said wall when spread to their gripping position, outwardly projecting teeth on the free ends of said gripping members where they extend beyond the wall of said inner member, the surfaces of said notches that face the end of the wall of the outer member being beveled, for the purpose specified.

at. A connecting piece for a tap comprising an outer member and a co-axial inner member forming no part of the tap but having a sliding movement relatively to each other, a series of gripping members pivoted each at one end in the wall of the said inner member so as to form part of said wall when spread to their gripping position,outwardly projecting teeth on the free ends of said gripping members where they extend beyond the wall of said inner member, the surfaces of said teeth that facethe end of the wall of the outer member being beveled, and means for spreading the said gripping members, for the purpose specified.
